RFE: New messages count

[tvercaut]

It would be great if firetray would support the display of the number of new messages similarly to what is proposed for the unread messages.

I understand that this RFE has been discussed here but the focus was not really on the count and the issue has been closed:
#13

Hi, that was my first intention when working on #13. Unfortunately, due to the unreliability of getNumMessages(), I gave up.
I'll try to see if counting directly in nsIMsgDatabase with getNewList() gives better results.
